Procedure 2-2 Powering Up the Frame
AT THE BTS SITE
For a +27 V DC powered UBS Macro frame, set the facility circuit breaker
controlling external +27 V DC power to the frame to the ON position.
For a — 48 V DC powered UBS Macro frame, set the facility circuit breaker
controlling external 48 V DC power to the PSM to the ON position.
For an AC powered UBS Macro frame, set the facility circuit breaker controlling
external AC power to the PSM to the ON position.
On the PDU, set the SSI circuit breakers to the ON position.
Check that the STATUS LED on the front panel of the each SSI is lighted.
For BTSs with more than one DMI, during troubleshooting or for forcing one
DMI to synchronize code and data with the other DMI, it may be desired to
bring up a particular DMI as the site master. In this case, power up the DMI
that should be site master first, wait 1 minute, and then power up the other
DMI that should be non-site master. The non-site master DMI will synchronize
its code load and base file with the site master DMI.
On the PDU, set the DMI circuit breakers for all of the equipped DMIs to the ON position.
Circuit breakers for any DMIs that are not equipped, should be set to the OFF position.
Check that the ST LED on the front panel of each DMI is lighted.
Confirm that the DMI fans are on and operating by listening for fan motor hum and
feeling that air is being exhausted from the rear of the DMIs.
On the PDU, set the XMI circuit breakers to the ON position. There may be up to four
XMI circuit breakers; XMI 1 through XMI 4. Circuit breakers for any XMIs that are not
equipped, should be set to the OFF position.
Check that the ST/ALM LED on the front panel of each the XMI is lighted. Confirm that
the XMI fans are on and operating by listening for fan motor hum and feeling that air is
being exhausted from the rear of the XMI.
On the PDU, set the ACC circuit breakers to the ON position only if there are accessories
connected to the PDU otherwise set these breakers to the OFF position.
10
If the BTS site is equipped with backup batteries, set all battery circuit breakers to the
ON position.
After powering up the frame, perform the steps in Procedure 3-3 Restore site
signaling operations procedure for a packet BTS on page 3-10.

Accessing OMCR CLI window
Many of the FRU procedures require the OMCR operator to manipulate BTS logical devices.
This is achieved using UNO or the OMCR (Operations and Maintenance Center - Radio)
Command Line Interface (CLI).
The operator enters commands using UNO or OMCR CLI.
The command dependent replacement procedures cannot be performed, if there are
any issues affecting the UNO or the OMCR CLI operations.
OMCR CLI access procedure
The following procedure is performed by the OMCR operator at the OMCR terminal.
Procedure 3-1 Login and access alarm window procedure
Login to the OMCR by entering the user name.
Enter the password at the system prompt.
Type CLI at the system prompt to open an OMCR CLI window.
Open an UNO Alarm Manager (AM) window by performing the following:
1.
Login to UNO as unoadmin
2.
Set the env variable DISPLAY to the IP address of the port where UNO
windows should be run.
3.
Type uno &. The main UNO window that was set previously should
appear on the display.
4.
Choose icon alarm manager from the main
uno window and set the appropriate filter
– OR –
choose Command Center icon -> BTSSDevices -> right click on
wanted bts icon and choose AlarmManager (filter will be set for
selected bts alarms).
Verify that the filter display is set to the BTS-# where the work is being
performed. This ensures that any BTS-# alarms, encountered while
installing the hardware, can be observed and rectified.

Shutdown site signaling functions for a packet BTS
If a complete site shutdown is required to support maintenance or upgrade operations, follow
Procedure 3-2 to disable the packet BTS site.
This site shutdown procedure takes the target BTS out-of-service (OOS) but does not
affect other BTSs. To minimize system impact, it may be advisable (but not necessary)
to perform this procedure during a maintenance window.
•
The EDIT BTS REDIRECT or REDIRECT2 command does NOT affect calls in
progress and does NOT move these calls to another BTS. The command prevents
future calls from being originated on the targeted BTS and also redirects
subscribers to another site/carrier. If active call processing is still taking place
in the target BTS, wait for any active calls to terminate before locking/disabling
the BTS resources.
•
Refer to the System Commands Reference manual for a complete explanation
of OMCR commands.

Packet BTS shutdown procedures
Procedure 3-2
Shutdown site signaling functions procedure for a packet BTS
At the OMCR
Open a CLI window. Refer to Accessing OMCR CLI window on page 3-3.
•
The recommended shutdown technique is to redirect subscribers to
another site/carrier and then wait for any active calls to terminate before
locking/disabling the BTS.
•
REDIRECT prevents future calls from being originated on the targeted
resource.
Perform one of the following:
•
To redirect subscribers and then wait for any active calls to terminate before disabling
the BTS, go to step 3.
•
To lock/disable the BTS when there is no concern for redirecting subscribers and
waiting for any active calls to terminate, perform step 23 through step 26 only.
The REDIRECT command is used to invoke the REDIRECT2 command which is then
used to redirect subscribers to a different CDMA carrier frequency. REDIRECT2 is
the preferred command if an alternate CDMA carrier is available.
Enter the following command at the prompt to display the status of the BTS signaling redirect
parameters for all carriers equipped for the BTS:
omc-000000>DISPLAY BTS- REDIRECT
Record the values shown in the system display response resulting from performing step 3.
These values are needed to answer the prompts for the EDIT BTS REDIRECT
command when restoring signaling operations at the end of the maintenance or
upgrade procedure.

This step edits the REDIRECT parameters so that the Global Service Redirect
Message to be broadcast on the paging channel redirects all subscribers away from
the BTS and onto a different BTS or system.
Enter the following command at the prompt:
omc-000000>EDIT BTS- REDIRECT!
The system prompts to enter each command parameter value one at a
time. Answer the prompts in the following order with the entries shown:
 enter Y,  enter Y, . . .  enter Y
(All Access Overload Classes must be set to yes to ensure that all subscribers are redirected.)
 enter N
(Must be set to no to ensure that subscribers do not return if redirect is unsuccessful.)
 enter 1 or 2
(A value of 2 will invoke REDIRECT2 which is used to
redirect subscribers to a CDMA channel at a neighbor site.
 enter 13
(Use the Area ID the subscriber units should expect to find on the system where they are
being redirected. This example uses 13. The valid range is 0–32767; the default is 0.)
 enter Y
 enter CUSTOM
(The system acquisition ordering value tells the mobiles the order to use when attempting to
obtain service on the different analog systems. Valid values are:
•
CUSTOM — use custom system selection
•
AONLY — try the A system only
•
BONLY — use the B system only
•
AFIRST — try the A system first. If unsuccessful, try the B system
•
BFIRST — try the B system first. If unsuccessful, try the A system
•
AORB — try A or B. If unsuccessful, try the alternative system
CUSTOM is the default.)
 enter 4
(Call processing continuously rotates in circular right-shifts, the Y/N values of Access
Overload Class Redirect Flags 0 to 9. Values are shifted one flag at the end of the timer
period; then timer restarts. Valid values are 0–255; 4 is the default.)

E-GPS Description
The E-GPS is located in the UBS Macro BTS frame and is mounted at the very top of the frame.
The E-GPS may be used instead of the optional Remote GPS (RGPS) head.
The E-GPS contains a GPS Receiver (GPSR) that requires connection to an external GPS RF
antenna signal. The E-GPS is considered to be local with respect to the UBS Macro BTS frame,
while the RGPS head is remotely located with respect to the UBS Macro BTS frame.
All cable connections to the E-GPS are made on the E-GPS front panel (see Figure 1-4 E-GPS
I/O Details on page 1-31).
The E-GPS SSI-GPS connector is cabled to the SSI RGPS connector. This connection allows the
UBS Macro BTS frame to supply DC power to the E-GPS. In addition, control/data signals are
exchanged between the DMI controller and the E-GPS via this connection.
The E-GPS GPS-ANT connector is cabled to the external GPS RF antenna cable connector. This
coaxial cable connection allows the E-GPS to receive RF signals from GPS satellites as well as
supply DC power to the GPS RF antenna preamplifiers.
The E-GPS receiver successfully tracks and acquires GPS satellites. The receiver detects GPS
RF signals and extracts a 1 Pulse Per Second (1PPS) timing signal. This 1PPS signal is applied
to the DMI controller via the SSI-GPS connector. The DMI controller contains an internal
Motorola Stability Oscillator (MSO) that is synchronized to the 1PPS timing signal and locked
to the GPS time base. If satellite tracking is lost or if the E-GPS fails, the MSO free runs, but
can maintain system timing for up to 8 hours.
If the UBS Macro BTS frame is equipped with an optional Quartz High Stability Oscillator
(QHSO), the DMI controller selects the QHSO as the backup synchronization source instead of
the MSO. The QHSO can maintain system timing for up to 24 hours.
System Impact/Considerations
Performing this replacement procedure should not require BTS downtime or impact
call processing because of MSO or QHSO backup. However E-GPS downtime will
occur. And alarms will be reported.

IDRF Description
The IDRF is available in either the 800 MHz or 1.9 GHz RF band.
The IDRF (Integrated Duplexer RX Filter) includes:
•
TX/RX bandpass filters
•
Bi-directional TX and RX antenna path couplers.
The IDRF is a passive device requiring no DC input operating power.
The IDRF allows the sector TX and main RX RF carrier signals to share the same antenna. It
also allows connection for a sector diversity RX RF antenna. The bi-directional antenna couplers
provide forward and reflected signal port connections for antenna signal sampling and signal
injection. The coupled ports are typically used for connection to test equipment.
The UBS Macro BTS frame is typically equipped with one IDRF per sector. Figure 1-2 Low
capacity UBS Macro BTS starter frame (1800 mm rack) on page 1-28 and Figure 1-3 UBS
Macro BTS mid-capacity frame (1800 mm rack) on page 1-30 show the location of the IDRFs
within the UBS Macro frame.
Figure 1-5 800 MHz IDRF I/O Details on page 1-32 and Figure 1-6 1.9 GHz IDRF I/O Details on
page 1-33 show the locations of IDRF RF I/O port connectors.
System Impact/Considerations
Performing this replacement procedure will cause downtime for all XMIs which will
suspend all call processing for the BTS.
The removal of a failed IDRF requires that all XMIs be dekeyed.
All of the XMIs will be disabled/locked to ensure that the transmitters are dekeyed. This will
interrupt all TX RF sector carriers.
Removal of the IDRF interrupts the associated sector TX/RX antenna paths.
Alarms will be reported during the replacement procedure.
After replacing an IDRF, the associated sector RX/TX paths must be optimized following the
procedure listed in the 1X UBS Macro BTS Optimization/ATP manual.

SSI Description
The first instance of the SSI is located in the right, front side of the IDRF shelf of the UBS
Macro BTS Frame. For SSI location, refer to the applicable Figure 1-1 UBS Macro BTS
low-tier/low-capacity frame (1000 mm rack) on page 1-27 through Figure 1-3 UBS Macro BTS
mid-capacity frame (1800 mm rack) on page 1-30.
For SSI connector identification, refer to Figure 1-7 SSI front panel details on page 1-35 and
Figure 1-8 SSI rear panel details on page 1-36.
The SSI housing has a built-in mounting mechanism (see Figure 1-8 SSI rear panel details on
page 1-36). This mounting mechanism allows the SSI to be mounted in the appropriate shelf.
One end of the SSI housing has two hooks that engage with two slots on the appropriate shelf.
The opposite end of the SSI housing has a right angle flange with two thumbscrews that secure
the SSI to the appropriate shelf.
The SSI operates from +27 V DC power supplied from a PDU SSI power connector that is
cabled to the POWER IN connector on the front of the SSI. A PDU SSI 20A circuit breaker
controls DC input power for the SSI.
The SSI contains I/O interface circuitry between the DMI and ancillary/external electronic
equipment. The specific equipment I/O and SSI connectors are as follows:

SSI replacement procedure
This procedure requires working on or around circuitry which is extremely sensitive
to ESD. Wear a conductive, high impedance wrist strap during the procedure. Use
appropriate safety measures.
For frames with more than one DMI — during the time that the SSI is powered
off or not connected to the DMIs, the DMIs will be rebooting continuously to try
to re-establish communication with the SSI. To minimize the number of reboots
that could eventually cause the DMIs to swap partitions to an older code load (i.e.,
10 reboots), perform the "AT THE BTS SITE" portions of Procedure 6-1 and then
Procedure 6-2 within 5 minutes. If this is not possible, it is recommended to power
off all DMIs when the SSI is powered off. Then, power the DMIs back up after the
new SSI is powered up.
To replace the SSI perform Procedure 6-1 and then Procedure 6-2.

Unbalanced E1 Daughter Card Description
The optional E1 daughter card is located on the front panel of the SSI.
For E1 daughter card location and connector identification, refer to Figure 1-7 SSI front panel
details on page 1-35 .
The E1 daughter card has a 37-pin connector on the bottom of the card. This connector plugs
into the SPAN 37-pin connector on the front panel of the SSI.
The E1 daughter card is secured to the SSI front panel via four corner screws.
The E1 daughter card is passive and does not require DC operating power. The circuitry on
the E1 daughter card transforms 75–Ohm unbalanced span line I/O to 100–Ohm balanced
SSI span line I/O.
The E1 daughter card supports up to eight span lines. It has 16 BNC connectors, 2 per span;
RX and TX.
System impact/considerations
Performing this replacement procedure will cause BTS downtime and impact call
processing.
The E1 daughter card is non-redundant. Alarms will be generated during the E1 daughter
card replacement procedure.
The E1 daughter card is hot swappable.

QHSO Description
The optional QHSO is located on the SSI rear panel (see Figure 1-8 SSI rear panel details
on page 1-36).
The QHSO is an upgraded backup synchronization source for maintaining BTS system timing
established/sourced by the E-GPS or Remote GPS (RGPS) head. QHSO backup is used instead of
the internal DMI controller Motorola Stability Oscillator (MSO). The QHSO can maintain BTS
system timing for up to 24 hours, as compared to 8 hours provided by the MSO.
The QHSO contains a high stability quartz crystal oscillator.
The QHSO has a 9–pin D-connector that connects to the HSO 9-pin connector on the SSI rear
panel. This connection allows the SSI to supply DC power to the QHSO. In addition, control/data
signals are exchanged between the DMI controller and QHSO through this connection. DC
power, control and timing information for QHSO operation is in the one connector between
the QHSO and SSI.
When the UBS Macro BTS frame is equipped with the optional Quartz High Stability Oscillator
(QHSO), the DMI controller selects the QHSO as the backup synchronization source instead of
the MSO. The QHSO can maintain system timing for up to 24 hours.
System impact/considerations
Performing this replacement procedure should not require BTS down time or impact
call processing because BTS system timing is being sourced by E-GPS or an RGPS
head. However, QHSO down time occurs and alarms are reported.
The QHSO is backed up by the MSO on the DMI controller board. Alarms will be generated
during the QHSO replacement procedure.
Call traffic processing through the BTS frame will not be interrupted by the QHSO replacement
procedure.
The QHSO is hot swappable.
SSI DC operating power will not be shutdown and SSI cables will not be disconnected during
the QHSO replacement procedure.

XMI Description
The XMI is available in either the 800 MHz or 1.9 GHz RF band.
The XMI contains sector RF transceivers and integrated sector TX RF Linear Power Amplifiers
(LPAs).
The XMI provides the BTS site RF air-interface for subscriber units and a high speed serial data
interface for transporting baseband data between the sector transceivers and the DMI modems.
One XMI is equipped for the low capacity UBS Macro frame. (See Figure 1-1 UBS Macro BTS
low-tier/low-capacity frame (1000 mm rack) on page 1-27 and Figure 1-2 Low capacity UBS
Macro BTS starter frame (1800 mm rack) on page 1-28.)
Two XMIs are equipped for the mid capacity UBS Macro frame. (See Figure 1-3 UBS Macro BTS
mid-capacity frame (1800 mm rack) on page 1-30.)
The XMI can support a UBS Macro frame in either an omni (1-sector) or 3-sector antenna
configuration.
An XMI in a UBS Macro frame can support the following quantity of carriers per sector:
•
For the 800 MHz and 1.9 GHz RF bands, one XMI in a 3-sector antenna configuration can
support 4 carriers with reduced TX RF power output per sector-carrier and up to 3 carriers
with full TX RF power output per sector-carrier.
•
For the 800 MHz RF band, 8 carriers per sector for an omni (1-sector) antenna
configuration.
•
For the 1.9 GHz RF band, 5 carriers per sector for an omni (1-sector) antenna configuration.
The XMI transceiver uses receive diversity for each sector.
For transmit, the XMI transceiver typically provides 2 - 30 W transmit RF output power per
sector/carrier (120 W total available RF power, when measured at the output of the UBS Macro
frame). In a 3-sector antenna configuration, the maximum TX RF power per sector-carrier is
20W.
The XMI operates from +27 V DC input power.
All external XMI I/O connections are made on the XMI front panel.

XMI (Transceiver Module Internal) Module
The XMI has the following items:
•
Main XMI processor/memory. This processor communicates with the XPAC, RX and TX
circuits, MMI and ENET (LMT) ports, and the controller in the DMI via the CPRI links.
•
Phase-locked loop (PLL) reference clock circuit that is synchronized to CPRI link serial
data input from the DMI. This clock reference signal is used to frequency synthesize all
RX & TX local oscillators.
•
DC power distribution which includes a +27 V DC input bus bar with four automotive style
fuses. These fuses provide protected + 27 V DC branch circuits, one for each sector LPA
and one for the transceiver (TX/RX) PCB.
•
Heat sinks and cooling fans. The cooling fans in the fan tray mounted on the rear of the
XMI draw air in from air vents on the XMI front panel through the XMI and exhausts air
out the XMI rear panel.
•
Internal wiring for PCB interconnection.
•

Chapter 7: XMI Replacement Procedures
RX Main & RX Diversity Signal Handling
In the UBS Macro frame, the main RX antenna signal from each sector IDRF (Integrated
Duplexer RX Filter) is applied to the corresponding sector main RX RF input of XMI 1. This
input is applied to the main receiver path of the corresponding XMI 1 sector receiver.
For low capacity frames with one XMI, the diversity RX antenna signal from each sector IDRF is
applied to the corresponding sector diversity RX RF input of XMI 1. This input is applied to the
diversity receiver path of the corresponding XMI 1 sector receiver.
For mid capacity frames with two XMIs, the main RX antenna signal from each sector IDRF is
applied to the corresponding sector main RX RF input of XMI 1. XMI 1 provides pre-amplified
main RX antenna signals at its RX EXP OUT connector. This connector connects to one of the
following:
•
optional RX splitter XMI 1 RX EXP IN connector. The RX splitter splits the main RX
antenna signal and distributes it to the RX splitter XMI 2 RX EXP OUT connector. This
connector is cabled to XMI 2 RX EXP IN connector. This connection provides the main
receiver path of the corresponding XMI 2 sector receiver.
•
optional XMI 1/XMI 2 RX cross-connect cable. This cable connects XMI 1 RX EXP OUT
connector to XMI 2 RX EXP IN connector. This connection provides the main receiver path
of the corresponding XMI 2 sector receiver.
For mid capacity frames with two XMIs, the diversity RX antenna signal from each sector
IDRF is applied to the corresponding sector diversity RX RF input of XMI 2. XMI 2 provides
pre-amplified diversity RX antenna signals at its RX EXP OUT connector. This connector
connects to one of the following:
•
optional RX splitter XMI 2 RX EXP IN connector. The RX splitter splits the diversity RX
antenna signal and distributes it to the RX splitter XMI 1 RX EXP OUT connector. This
connector is cabled to XMI 1 RX EXP IN connector. This connection provides the diversity
receiver path of the corresponding XMI 1 sector receiver.
•
optional XMI 1/XMI 2 RX cross-connect cable. This cable connects XMI 2 RX EXP OUT
connector to XMI 1 RX EXP IN connector. This connection provides the diversity receiver
path of the corresponding XMI 1 sector receiver.
The XMI automatically detects whether the RX signals are coming directly from the IDRFs
through the QMA cables or indirectly through the RX Expansion ports and adjusts its internal
RX gain accordingly. This automatic detection and gain adjustment occurs only during an
XMI power-up or reset.
XMI RX Output Signal Handling
Each XMI sector main/diversity receiver detects the RF RX carriers for the corresponding
sector. The detected main/diversity RX signals are A/D converted. These converted digital
signals are applied to the RX baseband control array. This array selects the best main/diversity
RX signals for the carriers assigned to the XMI.
The RX baseband control array outputs the selected RX digital signals to the RX
baseband bus. The RX baseband bus is applied to the Serializer/De-serializer & Data
Multiplexer/De-multiplexer. This stage multiplexes the RX baseband bus signals and converts
them to a high-speed serial data signal. This multiplexed RX baseband serial data signal is
applied to the high-speed serial data interface which provides 1.2288 Gbps links to the HSL
data ports on the front panel of the XMI.

XMI (Transceiver Module Internal) Module
XMI High-speed Serial data Links (HSL)
The XMI has redundant 1.2288 Gbps high-speed serial data links, one link per HSL 1 and HSL 2
data ports on the front panel of the XMI. These data ports, on the XMI, are connected to the
high-speed serial data interface on the DMIs.
The high-speed serial data link has a multiplexed serial data signal that contains RX/TX
sector-carrier traffic and overhead data as well as any DMI/XMI communications data.
TX Input Signal Flow
The multiplexed TX baseband serial data signal is applied, via the high-speed serial data
interface, to the input of the Serializer/De-serializer & Data Multiplexer/De-multiplexer. This
stage demultiplexes and deserializes the TX baseband serial data signal into TX baseband I
& Q output signals for each sector-carrier.
Each sector-carrier TX baseband I & Q signal is applied to the TX baseband control array. This
array conditions and combines all of the TX I & Q signals and then selectively routes them to a
pair of quadrature signal outputs for the appropriate sector (i.e., one pair per sector).
Each pair of quadrature signals is applied to the corresponding sector RF transmitter. The
quadrature signals are D/A converted and the resultant analog signal causes the sector
transmitter to output a low power multiplexed TX RF signal with the applicable FM modulated TX
carrier frequencies. This low power multi-carrier signal is referred to as the TX RF small signal.

XMI (Transceiver Module Internal) Module
Chapter 7: XMI Replacement Procedures
TX RF Small Signal Handling
For 800 MHz XMIs, the TX RF small signal from each sector RF transmitter in the XMI is
routed to the TXD connector on the front panel of the XMI. When the TXD connector is properly
terminated, each sector TX RF path is completed and the TX RF small signal from each sector
RF transmitter in the XMI is applied to the 3-sector TX RF input FTM. The FTM provides
3-sector TX RF output signals which drive the LPAs.
For proper operation of the XMI TX RF outputs, the XMI TXD connector must be
terminated with either a TXD attenuator or a TXD cable connected to a TX combiner.
Currently the 800 MHz UBS Macro BTS frame do not support the use of a TX
combiner, but it will in the future. Therefore a TXD attenuator must be installed in
the TXD connector on all 800 MHz XMIs.
For 1.9 GHz XMIs, the TX RF small signal from each sector RF transmitter in the XMI is routed
directly to the 3-sector TX RF input FTM. The FTM provides 3-sector TX RF output signals
which drive the LPAs.
The 1.9 GHz XMIs do not have a TXD connector.
In the future, the 1.9 GHz UBS Macro BTS frames will be equipped with 2:1 cavity
combiners that will connect to the TX output of the XMI LPAs.
TX RF Power Amplication
The 3-sector TX RF input FTM transforms the phase of each sector TX RF small signal. Each of
these phase transformed input signals drives the corresponding sector TX RF LPA section.
The sector TX RF LPA section amplifies the low power multi-carrier TX RF signal (i.e., TX RF
small signal) to the final XMI TX RF power output for the sector. (Note that each XMI sector TX
RF LPA section is capable of providing 30 W maximum TX RF power output). The final TX RF
power output signal of each sector TX RF LPA is applied to the 3-sector TX RF output FTM.
The output FTM transforms the phase of each sector final TX RF power output signal. Each of
these phase transformed sector output signals is applied to a corresponding RF coaxial switch
that is relay actuated. Each RF coaxial switch routes the sector final TX RF power output signal
to the corresponding sector TX RF output port (i.e., TX1, TX2 or TX3) on the XMI front panel.
The open/closed state of each RF coaxial switch is controlled by its associated relay. When the
relay is unenergized, its RF coaxial switch is open (N.O. = Normally Open). This condition
occurs when the XMI looses DC power and may also occur under XPAC control.
In the UBS Macro frame, the final TX RF power output signal from each sector of XMI 1 is
routed to the corresponding sector TX antenna via the corresponding sector IDRF.

XPAC Functions
The XMI PA Controller (XPAC) communicates with the XMI processor and controls/monitors
the following XMI circuits:
•
3-sector TX RF output FTM.
•
Three multi-carrier TX RF LPA sections; one LPA section for each sector.
•
Five cooling fans in the fan tray mounted on the rear of the XMI.
The XPAC and the XMI processor exchange control data and status/alarm messages via a
dedicated serial bus. The XPAC collects status/alarm inputs from each sector TX RF LPA, each
cooling fan and the TX RF output FTM. Then the XPAC reports this status/alarm information in
data messages to the XMI processor.
The output FTM detects forward/reverse power of each sector TX RF output and reports it to
the XPAC. If something like a sector antenna path with an extreme impedance mismatch causes
abnormal detected forward/reverse power, the XPAC will signal the respective FTM RF coaxial
switch relay to open the switch and block the sector TX RF output signal.
Each sector TX RF LPA has phase and power level sensors/controls throughout the LPA signal
path that the XPAC uses to dynamically increase/decrease the phase and power level of the
sector TX RF output signal as needed.
The XPAC monitors XMI and PA heatsink temperatures as well as the speed (TACH) of each of
the five cooling fans. The XPAC sends a Pulse-Width Modulated (PWM) DC control signal to
each fan to increase/decrease fan speed as needed to provide proper cooling.
System Impact/Considerations
Performing this replacement procedure in a UBS Macro frame with one XMI will
cause BTS downtime and suspend all BTS call processing.
Performing this replacement procedure in a UBS Macro frame with more than one
XMI will not cause BTS downtime, but will reduce BTS call processing capacity.
In the UBS Macro frame with one XMI, removal of the XMI has the following effects:
•
Interrupts the Main and Diversity RX signal paths for all sectors.
•
Interrupts TX RF output power on all sectors.
In the UBS Macro frame with more than one XMI: If XMI 1 is removed, the Main RX signal path
is interrupted for all sectors. If XMI 2 is removed, the Diversity RX signal path is interrupted
for all sectors.

XMI “HOT" Warning Label Details
The XMI has a “HOT" warning label attached to it (see Figure 7-1 for label location and
indications).
The hot warning label senses the surface temperature of the metal XMI housing. When the
XMI surface temperature reaches 50 degrees C, the “HOT" warning is fully visible indicating
that the XMI is too hot to touch and may cause burns. The “HOT" warning is partially visible
at temperatures that are slightly lower than 50 degrees C. When the “HOT" warning is not
visible at all, the XMI is safe to touch.

Prerequisites
Do not touch the XMI with unprotected hands when the “HOT" label is fully visible. If
the “HOT" label is fully visible, wear heat protective gloves when touching the metal
case of the XMI. The “HOT" label becomes fully visible when the temperature of the
metal case of the XMI reaches 50 degrees C. However, the label may be partially
visible at lower case temperatures.
The XMI module is heavy. Two people are required to lift, carry, or handle the XMI
module.
•
Be sure the removable XMI handle is attached to the front of the XMI before
physically handling the module.
•
Be sure two people use both hands and wear protective footwear when handling
the XMI.
•
Be sure to use two people to support the module while sliding the module out of
or into the shelf slot.
An XMI module that is not in a shelf should always be set on its side and never on
its edge. This will prevent the XMI module from tipping over and causing damage
or injury.
This procedure requires working on or around circuitry extremely sensitive to ESD.
Wear a conductive, high impedance wrist strap during the procedure.
Follow appropriate safety measures.
The XMI should be locked by the OMCR operator just prior to being removed.
